Sounds like the typical murican talking point. Trying to goad China into abandoning what's working for them so far to score some cheap ego points.I don't think China is a great power. They do nothing to prove they are. A great power acts with impunity, without hesitation, and without any regard for any law. China won't even dare take Taiwan that's like less than 200km away and is legally theirs. No great power allows itself to be surrounded on it's own border while spinning the "Do nothing and win air bender waiting around Sun Tzu focused chi" vinyl. We are being told to believe the US will just pack their bags and go home by themselves. It is a ridiculous construct.
The Han dynasty is a pussy and not a real power! They are letting the Xiongnu walk all over them with these agreements! They should attack them now instead of building up stuff behind the scenes and making sure they can crush them when the time comes!
Well ok they're not a great power. But they would rather be a winner at the end than being called a "great power".
